The WNT7a protein increases proliferation of muscle repair cells, a finding that could have implications for MD treatment

In experiments in mice, Michael Rudnicki, an MDA grantee at the Sprott Center for Stem Cell Research at Ottawa Hospital Research Institute (OHRI), and colleagues, found the WNT7a protein stimulates muscle repair by causing proliferation (an increase in number) of "satellite stem cells." They say the protein probably operates similarly in humans. The findings were published June 5, 2009, in the...

Long before "stem cell" became a household term, people had observed that plants and animals can, within limits, repair damage they sustain. Wounds heal, broken bones knit, and lost blood is replenished. Mowed grass soon regrows, and barren trees sprout new leaves in spring. Cut off a limb of a salamander or some other amphibians, and it regrows. But the limbs of other animals, once gone, can’t...
